Fuel Cell System

Teledyne’s proven proton exchange membrane (PEM) fuel cell technology provides excellent 4 efficiency and long life (>10,000 hrs.). The stack design is specifically tailored for operation with pure oxygen and includes design aspects 3 generated through years of experience with this technology. The fuel cell system features an 1 integrated balance-of-plant (BoP) with ejector driven reactant (EDR) technology for reactant recirculation. The BoP allows the fuel cell stack 3 to be fed reactants in a “dead-ended” 7 2 configuration maximizing energy delivery.

Reactant Storage

The fuel cell system is reactant storage 6 agnostic. Reactants can be suppplied via compressed gas, cryogenic, or solid-state reactant storage systems. The Subsea Power

Node is equipped with a compressed-gas reactant storage system. This storage system is

Specifications at a technology readiness level (TRL) of 9 and is commercially refillable.
